Ask the oncology nurses if they mind you coming into the unit to have your bloods done in future. That's assuming it is convenient for you to do so. Most oncology units seem happy for you to do that; they are the experts when it comes to veins and are very aware of our unique issues. At least you won't have to explain your concerns and they will take a bit of extra time with hot packs and other tricks to make it easier for you. Many of us have chosen to have portacaths inserted because of crappy veins and all the drama they entail.
